Learn about Process Instruction (PI) sheet functionality in SAP ERP Central Component 6.0 for the Production Planning-Process Industry (PP-PI). Get some tips and tricks on the use of PI sheets in error-free manufacturing data capture.
Key Concept

SAP ERP Central Component (SAP ECC) provides Process Instruction (PI) sheets as part of the Production Planning-Process Industry (PP-PI) component. PI sheets are primarily used in production processes in pharmaceutical, mining, chemicals, agro- based, and meat processing companies. They contain steps for processing or manufacturing a product and are generated from the control recipe in the process order. They are also used for communicating with third-party software such as Supervisory Control and Data Acquisition Systems (SCADA), and SAP modules such as materials management, production planning, quality management, and logistics execution. Process instructions in PI sheets can be executed automatically by the process control system or manually on a production line. SAP provides two types of PI sheets, ABAP-based and browser-based. The browser-based PI sheet is based on an HTML layout and is an enhanced version of an ABAP-based PI sheet.

In the process industry, production execution is closely integrated with other logistics functionalities such as batch management, quality management, inventory management, and product costing. This integration increases the complexity of data capture during the production execution and control – for example, performing a goods receipt that also does the inventory management posting or creating a batch while at the same time recording the values of the batch characteristics. As a result, the required data input is prone to data entry errors.

To combat this problem, we suggest configuring Process Instruction (PI) sheets. You can use PI sheet functionality to create an easy-to-use validation-based data input tool that enables error-free data capture with a significant reduction in user data input effort and cost.

Configuring PI sheets to meet your requirements is easy. We concentrate on how to build and integrate the custom scenarios in a characteristic-based and browser-based PI sheet. Browser-based PI sheets are enhanced versions of ABAP list-based PI sheets and contain helpful features such as input validation. We will explain how you can use the flexibility offered by PI sheet functionality for manual data capture for process orders in SAP ERP Central Component (SAP ECC) 6.0.

In addition, we provide a few tips and tricks for enhancing the PI sheet functionality provided in the standard SAP system. These tips and tricks are not well documented in either SAP Help or SAP Notes.
